Just bought a Sony VPCF11C5E. It's a quad-core at 2.4GHz with 4GB RAM. It's fast.
I installed ubuntu 10.04 yesterday, and it is running 99% perfectly after a change to xorg.conf to get the NVIDIA driver working.
Webcam, bluetooth and wireless all worked immediately.
To get sound, I had to install alsa-backports
The only thing not currently working is the built-in microphone (but I don't need one).
Most hardware seems to work "out of the box" with linux nowadays.
I am very happy
